Commercial and industrial gas-fired equipment -- products and standards
UL can evaluate commercial and industrial gas-fired equipment of over 400,000 Btuh to UL Standards including gas burners, boilers, furnaces, water heaters, air heater units and ovens. Tests can be conducted with both natural and propane gases. In addition, multi-fuel appliances such as gas/oil-fired burners and oil-solid fuel equipment can be evaluated. UL can also investigate equipment to Canadian requirements.
Commercial-industrial gas-fired equipment is evaluated to a number of UL standards, including the following:
| Standard | Title |
| UL 795 | Commercial-industrial gas heating equipment |
| UL 2096 | Gas and/or oil burning assemblies with emission reduction equipment |
| UL 2196 | Field-erected boiler assemblies |
For Canadian certifications, the applicable Canadian requirements are applied. For evaluation to requirements in other countries, CE Mark, or for other product types and combination fuel types, other Standards are applicable. UL can outline these requirements for manufacturers.
Testing logistics
- Location -- UL has fully equipped laboratories in several locations throughout North America, Europe and Asia Pacific where testing of these appliances can be conducted. UL also offers a program where testing can be conducted at the equipment manufacturer's facility and witnessed on site by a UL representative. UL can bring the necessary test equipment to the site, or the manufacturer's calibrated equipment may be used. Manufacturers who elect to conduct testing at their facility must comply with UL's data acceptance program (DAP).
- Specialty testing -- In some cases, a specialty product is built for a specific installation or customer. If requested, UL can conduct a field evaluation of these products and apply a UL field evaluated product Mark.
